We've stayed only 1 night, 2 adults and 2 kids (8,11) and had a chambre comfort. It was a studio on 2 floors, very nice decorated and confortable. The area is very nice, and close to the Danube ferry. The downside was that it was a bit warm at night, and when we left the windows open it was noisy from the night life. The hotel did offered ear plugs ans there was a fan in the room. But the area is very nice, with a lot if terrasses with live music.
One other a bit annoying thing, was the parking. The parking offered is actually a public one in the neighborhood. It is very close on foot, but by car it requires several maneuvers due to the one way streets. I wished we new upfront, from the info on the booking site.
The breakfast was good, and we could sit also on a nice terrasse.
Overall, we enjoyed it and we would come back.
